So its about the earnings, not the art as usual. I'm not surprised.
Personally I think if money is what you want, dont be an artist. Dont even try. It rarely pays. Thats one of the first things I was taught when I studied literature.
But if its art you want, to uplift the human spirit. To make us more than beasts, accept that its not about the money and make the sacrifices your art requires.
My advice to you, not that I think you'll care or listen to me, is stick to your job.
Maybe you will have time for art when you have reached retirement age.
